Yellowstone's Minute Geyser

This hot pool in Yellowstone National Park qualifies as a geyser because it erupts almost constantly. However, what you see is what you get. I like the color and texture of the heat-loving bacteria that live the perpetually hot environment of the pool. The changes in coloration are due to the distance from the vent. As the temperature of the water cools, the bacteria can no longer live and the coloration turns to white. You can tell that the landscape and the thermal formations are always changing by the two dead trees in the foreground.
